THAWING DEVICE FOR AUTOMOBILES.

Application filed December 13, 1824.. Serial No. 755,805.

To all whom it may concern:

Be it known that I, RICHARD BATTLE, a citizen of the United States,residing at Okmulgee, in the county of Okmulgee and State of Oklahoma,have invented certain new and useful Improvements in Thawing Devices forAutomobiles, of which the following is a specification. This inventionrelates to thawing devices, especially adapted for use in connectionwith water cooled engines.

Brieflystated, an important aim of this invention is to provide a steamcirculating coil which may be convenientlyapplied to the outlet pipe ofan automobile radiator without first detaching the outlet pipe or in anyway disturbing the hose connection of the same. I

' is of highly simplified construction, easy to apply and cheap tomanufacture.

Other objects and'advantages will be apparent during the course of thefollowing description. I i

In the accompanying drawing forming a part of this application, and inwhich like parts throughout the same Figure 1 is a perspectiveillustrating the improved thawing device applied.

Figure 2 is a vertical sectional view through the device applied. V

Figure 3 is a side elevation illustrating a slightly modified form ofinvention, the metallic cover being broken away tomore fully illustratethe coil.

Figure 4 is a side elevation illustrating another modification of theinvention, the jacket being broken away to illustrate the steam chamber.1

In the drawing wherein for the purposes of illustration is shown apreferred embodiment of the invention, the numeral 5 general- 1ydesignates a motor vehicle having an engine 6 and a water circulatingradiator 7 by means of which the heat in the water of the cooling systemis dissipated.

Fig. 2 clearly illustrates'that the bottom .of the radiator is providedwith a coupling member or outlet pipe 8 which is curved longitudinally,and has its rear end connected to a short hose 9. The upper end of theshort hose section pipe 11. I

This invention is shown in connection with a Ford automobile, butit isto be understood that the invention is capable of use in connection withany water cooled automobile engine. y

The improved thawing device consistsof a coil 12' having its upperterminal portion connected to the overflow pipe let of the radiator bymeans of a short coupling 15, and the coil is as shownin Figure 1,provided'with a plurality of convolutions or turns which'form somewhatof a nest to receive the major portion of the pipe 8. The coil or steamcirculating member 12 is more 9 is inturn connected to a or lesselongated'to conform to the longitudinally curved pipe 8, and theconvolu- ,tions of the steam circulating member are continuouslyinclined downwardly so that the products of condensation will not betrapped in thexdevice and possibly freeze.

- The presence of traps would allow the products of condensation tofreeze and defeat the purposes of the invention.

The lowermost convolution of the coil 12 ly at'an acute, angle toprovide an outlet 18, which extends through a metallic insulatingterial. The cover 20 surrounds the major portion of the pipe 8, andprotects the same from cold. The bottom ofthe metallic cover 20 isprovided with an opening 24 for the reception of the ,draincock 25 atthe intermediate portion of theoutlet pipe 8.

In carrying out the invention, the steam conducting member 12 is held inplace by loo.

plied without first detaching the short pipe 8 or disturbing any of thewater connections. This is so because of the peculiar formation of thecoil 12 which fits up under the pipe 8 and contacts with both of thesides of the same. When the coil 12 has been applied to the short outletpipe 8, the coupling member 15 which may be of any suitable material isemployed to connect the meeting ends of the overflow pipe 14, and thecoil 12 so as to establish communication between the dome of theradiator and the coil. The straps 26 and 27 are now employed to securelyhold the device in place on the pipe 8,andin case the water in the pipe8 or the radiator 7 freezes and the engine started, the resultant steamwill flow down through the overflow pipe 1% and through the coil 12 soas to melt the ice in the pipe 8.

It may be stated that the first place the water in the cooling systemfreezes is in the pipe 8 and in bringing about the meltingof any icewhich may be in the pipe 8, the circulation of water is resumed.

In the form of the invention illustrated in Figure 3 the inventive ideainvolved is the same as illustrated in Figure 1. The major differencebetween what is illustrated in Figures 1 and 2 and what is shown inFigure 3 resides in the fact that the coil 80 is provided with an abruptturn 81 which permits three convolutions to be employed at the forwardportion of the connection 8. The addition of the third convolution atthe lower portion of the connect-ion 8 substantially increases theradiating surface of the improved thawing device and consequently moreeffectively thaws the ice which may form in the connection 8. However,the addition of the third coil does not result in the formation of trapsas the inclination of the coil is. maintained. Therefore, the steam isconsequently flowing in a downward path and will not lodge in anyportion of the coil. This form of the invention employs a jacket 85similar in construction to the jacket 20 and held in place by fasteningdevices 86.

In the form of invention illustrated in Figures 4 and 5 the jacket is inthe nature of a nest shaped elongated body to be applied to the waterconnection 8 so that the steam chamber 91 in the jacket 90 will extendabout the major portion of the water connection to rapidly thaw ice inthe water connection.

The upper edge of the nest shaped body 90 is provided with an attachingneck 92 which may be joined in anysuitable manner as by a couplingmember 93 with the overflow pipe of the radiator.

The discharge from the steam chamber 91 is by way of an outlet 96arranged at the lowestportion of the device so as to carry off all steamwhich enters the chamber. Figure 4 plainly illustrates that the bottomof the nest shaped body 90 is provided with a centrally arranged opening97 to receive the drain member 98 of the water connection.

The outer side of the jacket 90 may be provided with a suitable heatinsulating medium to prevent the cold air from coming in direct Contactwith the steam containing jacket and condensing the steam therein.Suitable straps 99 are employed to secure the nest shaped jacket inplace.

in manufacture the improved nest shaped body may be stamped or otherwiseformed from two separate sections soldered or welded together. That isto say, the jacket is divided longitudinally or otherwise and the twoparts joined in any suitable manner. The jacket may be of two sheets ofcopper pressed to form with the edges soldered together and having thepipe connec;

tion fitted to it in any suitable manner for connection with theoverflow pipe.

The invention forming the subject matter of this application may becarried out by the employment of a cast iron jacket or pressed metaljacket with suitable baffles arranged to-divert the steam around and indirect contact with the bottom hose connection of the radiator.

Also the coil may be formed as an integral part of or soldered on to thebottom hose connection during the process of manufacture. Also asectional pressed steel jacket may be arranged about the bottom hoseconnection 8 and connected to the dome of the radiator by the overflowpipe or otherwise, so that the steam will flow around and come in directcontact with the pipe 8.

It is further within the scope of this invention to embed the coil inmolded asbestos tile without the use of the cover. It is thus seen thatthis invention is capable of a wide variety of mechanical expressions,and it is to be'understood that the form of the invention herein shownand described is to be taken merely as a preferred example of the sameand that such minor changes in arrangement and construction of parts maybe made as may remain within the spirit of the invention and scope ofwhat is claimed.

Having thus described the invention, what is claimed is:

1. A thawing device for use on automobile radiator outlet pipescomprising an elongated nest shaped body having a pocket to snuglyreceive the outlet pipe of the radiator whereby the body may be appliedto an automobile radiator outlet pipe without disconnecting the pipe,said body consisting of inner and outer spaced walls defining a steamchamber extending about the sides and bottom of the outlet pipe, and aninlet connected to the upper portion of said body and adapted forconnection with the overflow pipe of the radiator, the lowest point insaid body being provided with a steam outlet.
